Your battery negative to your shunt is sized at 2/0. Then from the shunt to the negative bus bar is also 2/0. The bus bar to frame ground only needs to be a #4 I believe. This should be the only bonding point. Don’t forget the equipment grounding conductor for your inverter as well. The size should be noted in your inverter documentation. Probably a # 8 or 10.

So I was grounding the shunt directly below it to the frame & then another 2/0 from the original frame grounding point to the negative busbar, do you think I'm ok with that .
Thanks for pointing out equipment bonding I forgot to add that in 8ga stranded.
Also all my measurements are from the center of the lugs.
